Title: Compact vibration reducing human support
Inventor: AMIN FEREIDOONI
IPC: F16F15/04
Filed: 2017-12-01
Abstract: An active vibration reduction system (VRS) for a human support is provided. The VRS has exactly two paths to ground in each degree of vibration reduction. One is provided by respective displacement actuators 10, 12 for active vibration reduction. The other is provided by one or more elastomeric damping bodies (EDB) 15. These paths extend from a bracket 18 for carrying a support structure for a live human to a grounding 16 for fixing the VRS in a vibrating environment. Each EDB is composed of a material having a dynamic Young's Modulus of 0.1-2.5 MPa, and a resilience test rebound height less than 40, and is positioned between the grounding 16 and bracket 18 to provide elastic restorative forces and damping in each of the respective directions. The use of EDBs simplifies construction, and allows for a more compact arrangement, without reducing vibration reduction efficiency.

Title: Methods and Devices for Tracking and Measuring Proof-of-Work Contributions in a Mining Pool
Inventor: ALEXANDER MACKAY
IPC: G06Q10/06
Filed: 2019-09-06
Abstract: Blockchain proof-of-work contributions made by miners within a mining pool are tracked by a pool master storing a Bloom filter. The Bloom filter stores candidate block header information submitted by miners during their proof-of-work searching. If a submitted block header is not stored in the Bloom filter, the Bloom filter is updated to store the block header. If a submitted block header likely exists in the Bloom filter, a count of invalid blocks associated with that miner may be increased. Block headers may be hashed and the result compared to a threshold difficulty value higher than the blockchain’s proof-of-work difficulty parameter. If the time of receipt between two block headers from the same miner deviates from a target, then the threshold difficulty value for that miner may be adjusted. In this way, submitted block headers may constitute regular partial proof-of-work reports by each miner. If the pool mines a valid block, a share of the reward may be allocated based on each miner’s associated difficulty threshold or the count of partial proof-of-work reports received from each miner. A relative share of rewards also may be allocated based on each miner’s invalid block or ‘bad hash’ count.
